Referring to Fig. 1 the casing of the rolliilm camera is provided with the customary film winding knob 2, which inthe interior of the casing is releasably coupled with a film take-up spool 2a in any well known manner. In accordance with the invention, a gear 3 is xedly attached to the stem of the knob 2 within the camera casing The gear 3 meshes with a gear I2 fixedly mounted on a rotatable and axially slidable rod d, which extends parallel to the axis of the film take-up spool 2a and forms the pivot axis of the swingable cover 5 of the camera casing A portion 3B of the circumference of the gear 3 is recessed and when this recessed portion 3 reaches the gear |2 the driving connection between the gears 3 and I2 is interrupted and the gear I2 returns independently of. the gear 3 to its initial position under the action of a torsion spring mounted around the rod 4.

The cover 5, when swung into open position, is maintained in this position by braces 6 as is Well known in the art. Preferably, lthe braces 6 are operatively connected to the camera objective mount A, so that the latter is automatically moved into operative position when the cover 5 is opened, thereby extending the bellows B which connects the objective mount with the camera casing. 'Ihe rod d extends with one of its ends outwardly of the camera. casing and this end is provided with a knob l which permits a manual operation of the rod by pushing it lengthwise inwardly for the purpose of releasing the previously tensioned shutter in a manner, as will be described presently. The shutter is built into or combined with the camera objective mount A as is customary in cameras of this type and is provided With a tensioning lever 22 and a release lever 23.

The rod t is provided between its ends with a thread I which is in engagement with an inte-- riorly threaded sleeve 8. The sleeve 8 is provided with a radial projection 9 in slidable engagement with a guide l0 fixed in the casing and extending parallel to the rod 4, so that the sleeve 8 is prevented from rotating about the axis of the rod 4. The sleeve 8 can move only lengthwise of the rod 4, either simultaneously with the same or without the same when the rod 4 is rotated.

The sleeve 8 supports rotatably a lever arm I8. which extends lengthwise of the cover 5 and has hinged to its forward end a plate I4 adapted to engage alternately the tensioning vlever 22 and the release lever 23. The ends of the hinge pin I3a are mounted in bearings I3b attached to the cover 5 in any desired suitable manner. A control rod I5 is pivotally connected with one end to the hinged plate I6 and with its other end engages a circumferential guide slot I6 on the sleeve 8. This arrangement has the purpose of tilting the plate I4 upwardly into operative position, when the cover 5 is opened (Fig. 2) and swinging the plate i4 downwardly into inoperative position against the inner face of the cover 5, when the cover 5 is closed (Fig. 3).

In order to prevent an actuation of the shutter release knob l as long as the film winding device has not completed its operation of moving the next unexposed film section in alinement with the photographic objective for exposure, a locking device of a known type, shown in Fig. 5, is provided in the upper portion of the camera casing I. This locking device is similar to the one described in the French patent specification No. 812,800 and includes a cam disc |'l which is connected iixedly or by a gear transmission to the film winding knob 2 and is prevented against return rotation by a ratchet pawl |'|a or the like. A locking disc I9, which is rotatable about the axis o f the cam disc has pivotally attached thereto at |8 a locking lever I8. One end of the lever |8 hasa. lateral projection I8b and is urged by a leaf spring I8c against the circumference of the cam disc Il. The locking disc I9 is urged by a coil spring 2| in clockwise direction, so that a projection |93 of said disc |9 tends to enter an axial groove 20 (Fig. 5a) in the stem of the shutter release knob 'I and enters this groove upon release of the locking lever i8 from the cam disc namely as soon as the shutter has been released once by depressing the knob I and the latter has returned to its initial position under the action of the spring II. A second actuation of the knob 1 is prevented, as shown in Fig. 5, by the projection I98L until the latter is withdrawn from the groove 2l) by an advance of the film. The other end of the locking lever I8 engages an inclined face 'i on the stem of the shutter release knob l. When the knob 'l is depressed, as illustrated in Fig. 5b, to release the shutter, the inclined face 'la causes the locking lever I8 to swing clockwise about its pivot axis |85, thereby releasing the other end I8h of the locking lever` i8 from the cam disc Il and permitting the spring 2| to move the projection |9a of the locking disc I9 in engagement with the axial groove 20. In this position the locking disc I9 has been moved clockwise away from the stop pin I9b (Fig. 5) and the end |8b of the lever I8 rests on the highest point of the cam disc il. The film winding device is now released and may be actuated to advance the film. When the lm Winding knob 2 has been rotated almost one-half a complete revolution, the cam disc I1 engages the end |8b of the locking lever I8 and moves the lever I8 including the locking disc I9 a suiiicient distance in counterclockwise direction to withdraw the projection i9 from the axial groove 20. In this position, which is illustrated in Figs. and 58 the locking disc i9 is again in engagement with the stop pin iSb, which prevents a further advance of the lm, and the locking lever i8 prevents a clockwise movement of the locking disc i9 until the release knob is again actuated.

When the lm winding knob 2 is rotated, the gear 3 drives the gear l2 and therewith the rod t is rotated. Owing to the threaded connection between the rod t and the sleeve t, the latter is moved lengthwise or upwardly (Fig. l) on the rod f1 and the lever arm i3 on the sleeve engages and actuates with its hinged plate it the shutter tensioning lever 22. At the time the lever 22 has been tensioned, the recess 3B of the gear 3 has y reached the gear i2, with the result that the gear i2 including the rod t, the sleeve i3 and the lever arm t3, itl return to their initial position, due to the action of the torsion spring li. When now the shutter release knob l! is depressed, the sleeve t including the lever arm i3 carried by the same, is moved in the opposite direction as during the operation of the film winding device to engage and actuate the shutter release lever 23.

Fig. 6 illustrates an embodiment of the invention in which the lever arm i3 oi the rst de= scribed embodiment is substituted by a lever arm 2t whose inner end is pivotally supported at 28a' in the camera casing l. This lever arm 25 consists of two parts connected with each other by a hinge 25 near the pivot axis of the cover E. The short part of the lever arm 26 is connected by a link 2d with the interiorly threaded sleeve 2i on the rod f3. The sleeve 2l is prevented in similar manner as in Fig. 1 from rotation by a fixed guide t@ in the casing i. The actuation of the sleeve il takes place in similar manner as described in connection with Fig. 1 by the gearing 3, l2 and the depressible knob i. When the iilm winding knob il is rotated, the sleeve 2l is moved in a direction in which the link 28 swings the lever arm 2&1 in engagement with the shutter tensioning lever 22 and actuates the same. A clepression of the knob l causes the sleeve 2l to move in the opposite direction, so as to effect an actuation of the shutter release lever 23 by the lever arm E63.

it locking device as described with reference to Fig. 5 is arranged between the lm winding knob 2 and the shutter release knob l, in fact, in all modications hereinafter described the saine locking device is employed.

Fig. 7 illustrates an embodiment in which a one-piece lever arm 29 is used for tensioning and releasing the shutter. The lever arm 29 is pivotally mounted between its ends on a pin 3U attached to the cover 5. The end of the lever 29 which projects into the camera casing i carries a pin 3i engaging an annular groove of the sleeve 32 which is in threaded engagement with the shutter operating rod 4. The sleeve 32, in

l similar manner as the sleeve 8 (Fig. l) is prevented rorn rotating by a stationary guide 33. When the film winding -knob 2 is rotated to wind an exposed section ofthe film upon the takeup spool 2a, the shutter operating rod 4 is simultaneously rotated by the gearing 3, l2 resulting in an upward movement of the threaded sleeve 2l and in a swinging movement of the lever arm 29 about its pivot pin 30, thereby effecting an actuation of the shutter tensioning lever 22. A subsequent depression of the knob l on the rod 4 causes a movement of the threaded sleeve 33 and the lever arm 29 in the opposite direction, thereby actuating the shutter release.

lever 23.

in the embodiment of the invention illustrated by the Figs. 8 to 11, the shutter operating rod (i, which also forms the pivot axis of the cover 5, is provided in similar manner as in Fig. l with an interiorly threaded sleeve M provided with an annular groove rotatably receiving a ring 3E. The sleeve 31B is prevented from rotating by a stationary guide 35. The ring 3S has a short radial arm 3l provided with an oblong aperture Bla. A lever arm 39 is pivotally mounted between its ends about a pin li@ on the cover ii and one of its ends carries a pin 3S engaging the oblong aperture 3l in the radial arm till. The other end of the lever arm Sil which is directed toward the photographic objective and the shutter is provided with lateral iianges 38e (Figs. l() and il.) which gradually approach each other, so as to form a narrow throat at its extreme outer end. The throat is adapted to receive a radial pin (il on a ring ft2 which is rotatably mounted on the mount A which contains the photographic objective and the shutter. The ring t2 has thereon an arc-shaped projection 413, one end of which is adapted to engage and actuate the shut. ter tensioning lever 22, while the other end is adapted to engage and actuate the shutter release lever 23. The nenges 39S engage alternately opposite sides oi the pin fli to cause a rotative movement of the ring i2 in opposite direction when the lm winding knob t and the shutter release knob l are actuated respectively. The throat formed between the iianges 39 oi the lever arm 3Q widens toward its pivot axis for the reason to insure an entrance of the pin il between the anges 3Q when the cover 5 is opened, even though the shutter may not have been completely wound up or tensloned.

In the embodiment illustrated by the Figs. l2 and 13 the gear connection 3, l2 is substituted by a cam groove connection and the cover 5 is pivoted about an axis extending at a right angle to the axis of the take-up spool 2a. As shown in Fig. 12, the stem of the illm winding knob 2 has lxedly attached thereto a cylindrical disc Lt@ having a cam groove MB in its circumferential surface. A pin it xedly attached to an axially slidable rod projects into the cam groove t4, which has such a shape, that after each advance.. ment of the lrn about one picture frame the pin it will occupy an axially extending portion Sb of the cam groove MB. In this position the rod l5 which has been raised by the cam groove MS is returned to its initial position (shown in Fig. l2) by a spring I'l. The outer end of the rod t5 is provided with the shutter release knob l. A compression spring te is mounted on the rod :i5 between the pin Mi and a disc 4B resting loosely against a cross pin 5i. The spring C9 is stronger than the spring 4l, so that the disc t8 is urged against a stationary abutment in the camera casing i. The axial movement of the rod i5 is transmitted by a bell-crank lever 53 to a sleeve which is slidablx7 mounted on a pin 54 forming the pivot axis of the cover 5. One end of the bell crank lever 53 is bifurcated and engages a cross pin 52 on the rod S5. The other end of the bell crank lever 53 engages an annular groove 56 of the sleeve 55. A lazy tongs structure 5l is attached with one end to the sleeve 55 and with the other end to a plate 58 having an upwardly bent ange 59 which is attached to the arc-shaped projection i3 of the ring d2 which, as shown in Fig. 9, is rotatably mounted on the mount A containing the photographic objective and the shutter.

Assuming that'the shutter has been released, the locking device, as illustrated in Fig. 5, will be in a 'position in which the lm winding knob 2 can be rotated to wind up the exposed section of the nlm. When the knob 2 is rotated the pin (i is raised by the cam groove tide, thereby moving the rod Q5 upwardly and rotating the bell crank lever 5l in clockwise direction. 'I'he sleeve 55 including the lazy tong structure 5l is moved toward the left, thereby rotating the ring l2V clockwise until the shutter tensioning lever 22 has been actuated. At this point the pin it has reached the axially extending portion Mib of the cam groove 36a and the spring il returns the vrod 65, and therewith the sleeve 55 and the lazy tongs structure 5i to their initial position as shown in Figs. 12 and 13. Now the shutter release knob 'i can be pushed downward against the action of the spring la to eect a movement of the bell crank lever 53, the sleeve 55 and the lazy tongs structure 5T! in the opposite direction, so as to actuate the shutter release lever 23, Upon release of the knob l the spring i9 returns the rod dii, the bell crank lever 53 and the lazy tongs structure 5t to the normal position shown in Figs. l2 and 13.

The modification of the invention as illustrated by the Figs. 14 to 16 dliers principally from the embodiment just described with reference to the Figs. l2 and 13 by the employment of the shutter control rod i as pivot axis for the cover 5 of the camera. The shutter control rod l, in the same manner as in Figs. 1 to 5, is connected by a gearing 3,52 (Fig. 4) with the nlm winding device 2 and is rotated by the latter whenever a section of exposed nlm is wound upon the take-up spool 2a. Such a rotation of the rod i moves the interiorly threaded sleeve on the upwardly on the rod l to tension the shutter (Fig. 14). The stationary guide i@ prevents a rotation of the sleeve at. The threaded sleeve 6@ has one end of the lazy tongs structure 5l attached thereto, while the other end ofthe same is connected to the rotatable ring d2 on the mount A in the same manner as shown in the Figs. 12 and 13. The operation of this modied embodiment is believed to be obvious in view of the previously described embodiments.

The Figs. 17 to 19 illustrate an embodiment of the invention in which the rotatable and axially shiftable shutter control rod Si and the axis of the take-up spool 2a are arranged at a right angle with respect to the pivot shaft 62 of the cover 5 of the camera. A bevel gearing S3, @il connects the shutter control rod Si drivingly with the pivot shaft 62 (Fig. 18). The bevel gear 53 is rotatably journaled in a bearing @3B of the camera casing and thus is prevented from moving in axial direction. The lower end l of the shutter control rod 6I is square in cross section and extends slidably through a corresponding square bore of the bevel gear 63. 'I'he pivot shaft a2 supports slidably an exteriorly threaded sleeve 66, which by means of a key $5 is drivingly connected with the shaft $2. The sleeve 66 in turn supports an interiorly threaded bushing 51, which is prevented from rotating by the stationary guide l0. A lever arm 68 is pivotally mounted with one end on saidV bushing 6l, while the other end of the lever arm 68 extends forwardly to the mount A containing the photographic objective aesaeer and the shutter, so as to be able to actuate a1- ternately the shutter tensioning lever 22 and shutter release lever 23.

The shutter control rod carries a bushing e@ provided with an outwardly extending arm l@ engaging one leg of a bell crank lever li, whose other` leg engages an annular groove 12 near one end of the exteriorly threaded sleeve sti. When the knob l on the upper end of the rod @i is manually depressed,l the sleeve 66 and the bushing al thereon vis moved toward the right, so that the lever arm Bt actuates the shutter release lever 23. This actuation of the shutter release lever 23, owing to the locking device illustrated in Fig. 5, can only take place after a pre- .vious actuation of the tensioning lever 22, which is done by the lever arm 68 during the operation of the film winding device 2.

The Figs, 20 and 21 illustrate a modication of the embodiment of Fig. 12, in that the lazy tongs structure is substituted by a single lever l5. This single lever i6 is plvotally attached between its ends at les tothe cover 5 of the camera.

VOne end of the lever l@ has-a pin i5 engaging an annular groove ll in a sleeve 13 axially movable on the hinge rod 5d. The axial movement of the sleeve i3 is controlled, in the same manner as in Fig. 12, by a bell crank lever 53, one leg of whichengages an annular groove 5d of the sleeve i3. terminates in an upwardly bentv portion la adapted to alternately engage the shutter tensionlng lever 22 and the shutter release lever 23.

According to Fig. 22 the shutter release knob 'i is mounted on a rod il, which is coaxial with the pivot axis of the cover 5 of the camera and forms one bearing of one of the two bearing arms 5H of the cover 5i. The other arm 5 is mounted on a separate bearing pin lil attached to the camera casing l, The inner end of the rod il engages an angularly bent end 83 of a shaft ad rotatably mounted in bearings Sile on the inside of the cover 5.' The other end 85 of the shaft @il is also bent angularly with respect to the axis of the shaft and lies adjacent the shutter release lever 23 to aetuate the same when the release knob 'ion the camera casing l is depressed.

The shutter tensioning lever 22 is actuated by a lever arm i8 which consists of two parts hingedly connected with each other at '18B in the pivot axis of the cover 5. The short part of the lever arm 'i8 is rotatably attached to a sleeve 80, which is in threaded engagement with a shaft 32 arranged parallel to the pivot axis of the cover 5. A stationary guide 19 prevents a rotation of the sleeve 80 on the shaft 82. A torsion spring 8i, which surrounds the shaft 82, returns the same to initial position (Fig. 22) after each actuation of the tensioning lever 22. This return movement takes place as soon as the gear l2 enters the recess ta in the gear 3.

In the embodiment shown inl Fig. 23 the iilm winding device 2 is drivingiy connected with the shutter control rod t5 by a cam drive lit, d6 in the same manner as in Figs, 12 and 20. However, the shutter control rod l5 is arranged in a different manner, namely directly in the pivot axis of the cover 5 of the camera. A sleeve 3S. which is prevented from rotating by a stationary guide 8l, is slidably mounted on' the rod Q5 and has an annular groove engaging a pin 88 on one end of a lever arm 89, the other end of which is adapted to alternately actuate the shutter tensioning lever 22 and the shutter release lever 23.

The other end of the lever i6 l The lever arm 89 is pivotally supported between its ends on the cover at 89B. When the knob 2 is rotated for winding the nlm' upon the spool 2, the shutter lever 22 is actuated by the lever arm 89, and when the knob 'l on the camera casing I is depressed the lever arm 89 is swung in the opposite direction to actuate the shutter release lever 23.

The camera shown in Fig. 24 is provided with two separate means for tensioning and releasing the shutter. The shutter release device is constructed the same as illustrated in Fig. 22, except that the rod 'l'I is not in alinement with the pivot axis or the cover 5but parallel thereto. Therefore, similar elements have been provided with similar reference characters. The film winding knob -2 is provided on the inner portion of its stem with a cam 90 for actuating a rectangularly bent rod Qi the long leg of which is in axial alinement with the pivot axis of the cover 5. A collar 93 on said long leg of the rod Si, which by means of a guide 92 is prevented from rotating, engages with a groove a pin 9d on one end of a lever arm Q5, the other end of which is adapted to actuate the shutter tensioning lever 22. The lever arm 95 is pivotally mounted between its ends on the cover 5 at 95e. A tension spring 96 urges the rod @i downwardly and maintains the short leg of the latter in engagement with the cam sii. When the lm Winding knob 2 is rotated to wind the film upon the take-up spool 2a, the cam Si raises the rod @I against the tension of the spring 96 and the lever arm S5 is oscillated to actuate the shutter tensioning lever 22.

According to Fig. the cam 96 on the nlm winding knob 2 controls the axis movement of a sleeve 98 by means of a radial pin 9i on the latter. Thesleeve 98 is mounted loosely on an axially slidable rod |102, whose upper end projects from the camera casing and has the shutter control knob l! attached thereto. A spring Qa urges the sleeve Siti downwardly and maintains the pin 97 in engagement with the cam Sid. A collar @Si attached to the sleeve 98 is connected by a link i0@ with a lever arm IIii having a hinge iIlI near the pivot axis of the cover 5. One end of the lever arm IGI is pivotally supported in the camera casing at Iliib and the other end is adapted to actuate the shutter tensioning lever 22. The lower end of the axially slidable rod H32 projects from the sleeve S8 and engages the angularly bent end H03 of a shaft |04 rotatably supported on the cover 5 at 604e. The other end i5 of the shaft IM is also bent angularly, so as to actuate the shutter release lever 23 when the knob I is pushed downwardly. A spring which is not shown in the drawing maintains the 'rod I 02 normally in a raised position. The Figs. 26 and 27 illustrate another embodiment in which two separate members |06 and II8 are employed for actuating the shutter tensioning lever 22 and the shutter release lever 23 respectively. 'I'he lever arm |06 for actuating the tensioning lever 22 is rotatably mounted on a sleeve |07 having an inner thread in engagement with a corresponding outer thread on a shaft |08, whose axis is coincident with the 'pivot axis oi the cover 5 0f the camera. A bevel gearing |09, i iii connects the shaft |08 with a shaft I I2, which is mounted parallel to the axis of the lm takeup spool 2E and is connected with the lm winding knob 2 by the gearing 3, I2 previously described with reference to Fig. 4. A torsion spring I II around the shaft I I2 returns the latter and therewith the sleeve |01 on shaft |08 and the lever arm |08 to initial position as soon as the tensioning lever 22, at the end of each lm winding operation, has been actuated. The lever arm |06 contains a hinge |068 near the pivot axis of the cover 5, so as to permit a closing of the camera. The shutter release knob 'l on the camera casing I actuates a slidably mounted rod II3, which in turn bymeans of a bell crank lever IM actuates a yoke H5, one end |2i of which is slidably supported by a reduced portion |20 of the sleeve Ilil while its other end |122 is slidably supported by a smooth portion of the shaft I t28. A pin |23 projects upwardly from the portion of the lever arm I 05 encircling the sleeve Iill and projects through an axially extending slot I I6 in the yoke I I5. rThe end I22 of the yoke H5 is integrally formed with a hook-like portion |25 engaging an angularly bent end portion III of a shaft IIB, which is rotatably-supported in bearings |26 on the inside of the cover 5. The other end I|9 of the shaft i Itiislikewise bent angularly and terminates adjacent the shutter release lever 23 to actuate thesame when the knob 'i is depressed. A spring 628 urges the yoke H5 normally toward the left and returns the yoke II 5 including the rod I I3 to normal position after each actuation of the shutter release lever I23. When the lm winding knob 2 is rotated, `the gearing 3, I2 rotates the shaft H2, which in turn rotates the threaded shaft Hi8. The threaded sleeve Iii'i, which is preventing from rotating, is moved toward the left and thereby the lever arm ISG actuates the shutter tensioning lever 22.
